Thanks.  I read through the patch and it all looks good to me.

Julian>     include/

This has to be approved on the gcc side, but then it is fine to import.
Or you can wait for one of my more or less random mass imports.

Julian>     gdb/
Julian>     * dwarf2read.c (dwarf2_add_member_fn): Add calling convention
Julian>     argument to smash_to_method_type call.
Julian>     (quirk_gcc_member_function_pointer): Likewise.
Julian>     (read_tag_ptr_to_member_type): Likewise.
Julian>     (smash_to_method_type): Add CALLING_CONVENTION argument. Initialise

Julian>     (init_type): Call INIT_FUNC_SPECIFIC for method types as well as

Julian>     * gdbtypes.h (struct main_type): Adjust comment for FUNC_STUFF.
Julian>     (struct func_type): Adjust comment.

This is ok contingent on the gcc patch.
